## Description

Product Description pH is the measure of acidity of water, on a scale ranging from 0 to 14. A pH of 0 is the most acidic, while a pH of 14 is the most alkaline. Different geographies have different tap water conditions with different pH levels, while fish require a specific pH level to thrive. A pH of 7.0 is ideal when keeping a community aquarium containing a variety of tropical fish. Goldfish and livebearers prefer a pH of 7.5. Many desertcartian fish, like angelfish and neon tetras, prefer a pH of 6.5 to 6.8. Mollies and swordtails thrive at pH 7.2 to 7.5. API pH UP Freshwater Aquarium Water pH Raising Solution raises aquarium pH in freshwater aquariums to desired level. Safe for fish and plants. Use when setting up a new aquarium, adjusting pH, or changing water. pH in an aquarium can fluctuate due to fish waste, uneaten food and addition of tap water. It is recommended to test water for pH weekly. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium.

## Questions & Answers

**Q: Is this safe to use with live plants in the tank**
A: It's fine to use with live plants

**Q: How much water does this treat?**
A: A huge amount. 5ml treats 190 L of aquarium water. Each bottle holds 118ml. I make that 23 treatments for a 190 L aquarium!

**Q: How much can put this in 6.8l aquarium?**
A: Not sure but the instructions are on the bottle. Mine is 180L so it's 5ml for every 38L. So for you, 0.8ml or 1ml.

**Q: Is this product suitable for saltwater?**
A: No it is not suitable for saltwater aquariums. It will raise certain elements and cause a white bloom/haze. You could try baking soda ( bicarbonate of soda ( 1 teaspoon per 20 gallons of water but introduce it very slowly) hope this helps.

### ⭐⭐⭐⭐ Works as described
*by C***C on 2 May 2022*

Lowers ph but sometimes this just hides the cause! So if you are looking into this make sure it’s not another factor? Do you have too many fish? Is your tap safe not right? Need a new filter pad?
